TL;DR: An alternative method is proposed, introducing generalized k0 factors which are independent of irradiation and measuring conditions, which combines the simplicity of the absolute methods with nearly the same accuracy attained by the relative ones.
Abstract: A critical evaluation of different comparator methods is given. The method based on experimentally-determined and convertible comparison factors (k) is considered to be the most suitable for general use. An alternative method is proposed, introducing generalized k0 factors which are independent of irradiation and measuring conditions. This approach combines the simplicity of the absolute methods with nearly the same accuracy attained by the relative ones. It is suggested that k0 factors be compiled in all cases when using single-comparator methods, to allow a continuous re-evaluation.

TL;DR: In this paper, the accuracy of literature data for 112 radionuclides of interest in (n, γ) reactor neutron activation analysis is compared with the values calculated from the experimentally determined k0-factors.
Abstract: k0-Factors and related nuclear data are tabulated for 112 radionuclides of interest in (n, γ) reactor neutron activation analysis. Whenever relevant, critical comments are made with respect to the accuracy of literature data for e. g. isotopic abundances, half-lives, absolute gamma-intensities and 2200 m · s−1 (n, γ) cross-sections. As to the latter, a comparison is made with the values calculated from the experimentally determined k0-factors, by introduction of selected literature data for the input parameters.

TL;DR: In this paper, a spectrophotometric method is described for the determination of nitrate in the 0.5 to 50μg range using chromotropic acid as the reagent and masking agents for the elimination of possible critical interferences due to chloride, chlorine, iron(III) and oxidants.
